在mex函数中将特征复数矩阵返回给matlab，而无需额外复制

#include "mex.h"

void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
    // Check input and output arguments
    if (nrhs != 1)
        mexErrMsgIdAndTxt("MyToolbox:arrayProduct:nrhs", "One input argument required.");
    if (nlhs != 1)
        mexErrMsgIdAndTxt("MyToolbox:arrayProduct:nlhs", "One output argument required.");

    // Get input matrix
    const mxArray *inputMatrix = prhs[0];

    // Get input matrix dimensions
    mwSize numRows = mxGetM(inputMatrix);
    mwSize numCols = mxGetN(inputMatrix);

    // Allocate output matrix
    mxArray *outputMatrix = mxCreateNumericMatrix(numRows, numCols, mxCOMPLEX_DOUBLE);

    // Get pointers to output matrix real and imaginary parts
    double *realPtr = mxGetPr(outputMatrix);
    double *imagPtr = mxGetPi(outputMatrix);

    // Perform computation and write results to output matrix
    // ...

    // Return output matrix to Matlab
    plhs[0] = outputMatrix;
